From a reader:

Jonah, The Oxford series on sin is, in my opinion, mediocre. It’s interesting only in that it’s an under discussed topic these days. Even in Christian Evangelical circles who like to obsess over Sin there really is very little consideration of the sins themselves. Cornelius Platinga has a great little book on sin called Not the Way its Supposed to Be, in which he defines sin as breaking of shalom. Also interesting is The Seven Deadly Sins with a foreword by Ian Fleming. A few decades ago he gathered literary luminaries to write their musings on sins. Hit and miss, but culturally interesting. The best contemporary book, however, is by far The Seven Deadly Sins by Solomon Schimmel. He’s a Jewish writer who looks at the sins from the perspective of a variety of traditions. Very well written, very insightful all around. Of course, in my mind the absolute best source for looking at this topic is to go back to the earliest sources. I’m not good on the Jewish/Rabbinic side, but the early Christian monastics talked a lot about this, and in ways that are surprisingly balanced and insightful. John Cassian’s The Institutes is a great initial resource, but to get into it more thoroughly having a look at Evagrius’ complete works seems vital. He’s the guy who popularized the list of deadly sins, though in his list its 8 not 7. As you might be able to tell it’s been a research interest, and maybe writing interest of mine as well.
